摘要：
A perforating gun assembly for use in a wellbore. The perforating gun assembly includes a carrier gun body and a charge holder disposed within the carrier gun body. A plurality of shaped charges are supported within the carrier gun body. A secondary pressure generator is operably associated with at least one of the shaped charges. The secondary pressure generator optimizes the wellbore pressure regime immediately after detonation of the shaped charges by controlling the dynamic underbalance created by the empty gun chambers to prevent excessive dynamic underbalance which may detrimentally effect the perforating operation.
摘要（中）：
用于井眼的穿孔枪组件。 穿孔枪组件包括载体枪体和设置在载体枪体内的电荷保持器。 多个成形的电荷被支撑在载体枪体内。 二次压力发生器与至少一个成形装置可操作地相关联。 二次压力发生器通过控制由空枪室产生的动态欠平衡来立即优化成形电荷引爆后的井筒压力，以防止过度的动态欠平衡，这可能不利地影响射孔操作。
